about blank problem

Hi, I am new here and I know other people have had this problem but I didn't want to copy their instructions if it is different for me.

We have been getting about:blank homepage for the past week now. No matter what I do it comes back. And now from deleting things I guess, when I type in posts it takes forever for the actual charaters to show up.

After I run the programs below I try to install spware blaster 6 and get this message: This program has been damaged, possibly by a bad sector of the hard drive or a virus. Please reinstall it.

I ran Adaware and got 11 new items. I also ran CW Shredder and got 6 items. I removed them all and ran hijack this. Here is my log.

Any help would be appreciated as this is driving me crazy. Also, my husband and I have different logon names so whatever I do under my login doesn't seem to apply for his. So I think that may also be hurting me.

Next, do this:
open the registry from start/run/regedit
And expand the following:
*HKEY_CLASSES_ROOT\PROTOCOLS\Filter
RightClick the 'filter' key, choose 'export' name it and save in location of choice

Navigate to this key next:
*HKEY_LOCAL_MACHINE\SOFTWARE\
Microsoft\Windows NT\CurrentVersion\Windows
Find this value on the right panel:
"Appinit_Dlls"< RightClick and rename to:
->'Appinit_Dlls1'
Close regedit, reopen it to the same key, Hilite the
'Windows' key there,
Export it the same way and save in location of choice

Lastly, navigate to:
*HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\
Windows\CurrentVersion\Explorer\
Browser Helper Objects<
Export that Subfolder the same way.
And proceed to do the following:

RightClick Security/permissions on 'Browser Helper Objects'
in 'advanced, de-select (uncheck) the
"inherit from parent...permissions" lower box.
Hit ok' and 'remove' on next prompts.

That will prevent it from spreading further.

Into your next reply, navigate to the .reg files
you saved, RightClick each -> edit, copy the
contents and post here, along with new hijackthis log.
